Hydraulic Enclosures is a cabinet built to transmit sound to the gamer through mounted loud speaker drive components. The major role of this loud speaker enclosure is to avoid the out of phase sound waves of the back of this speaker out of combining with the in phase sound waves from the front of the speaker. This ends in port patterns and cancellation, inducing the efficiency of these speakers to be reduced; particularly from the low frequencies where the wavelengths are so high that disturbance can affect the entire listening area.

Many loudspeaker enclosures use some type of structure, more like a box to comprise the out of phase sound energy. The box has been made of wood or, even more recently, plastic, both for the grounds of easy structure and appearance. Loudspeaker cabinets are occasionally sealed and some times ported. Ported cabinets allow a number of the noise energy inside the cabinet must be discharged, and when designed properly with good focus to phase relationships, both increase bass response and reduce driver excursion.

Many other technology variations on the basic box design exist, such as for example acoustic lines. Enclosures always play a substantial role in sound production in addition to the planned design impacts, adding regrettable resonances, diffraction, and other undesired phenomenons. Problems with resonance are usually reduced by increasing enclosure mass and rigidity, by hightened damping of enclosure walls, or even by adding absorption .

Bass Reflex or vented loudspeaker enclosure

Vented or bass enclosures require special structures due to the big forces which can be developed by the drivers installed indoors the act on them. Vented loud speaker enclosures have two principal purposes - the separation of vibrations from front and back of their loudspeakers, and the containment of air in order that the air can act as a resonating elastic moderate inside the enclosure.

Vented enclosure functioning is analogous to how a bottle will act as a whistle. At a system that is ventilated it is important to prevent air leaks, since the vent produces most of the noise at the frequency of resonance and the pressure in the enclosure could be significant.

Air flows in the walls or tiles of the enclosure can create the tuning of the system to shift in frequency, so producing other undesirable effects also. The material used for enclosure walls should be sturdy and dense and should be free of voids or warps. The ideal loudspeaker enclosure might have no wall space in frequencies which fall within the frequency selection of loudspeakers mounted in it. 25 millimeters solid lead plate would create an fantastic loudspeaker enclosure.



Electrical filter theory has been used with considerable success for woofer and subwoofer enclosures.
